Generally a successful migration plan consists of three main sections, namely Readiness Assessment, Planning, Migration and Modernization Phase. Let's talk about each section briefly.
The very first step of a successful migration is the assessment of the current state. You should beforehand assess your businesses current state to operate in the cloud and identify the desired achievements and business outcomes. You should also develop cases for migration.
After the readiness assessment, you are ready to create a migration plan and optimize your cases. Identifying gaps in your operations that were uncovered in the assessment is the first key. You should focus on building a base environment, improving cloud skills and directing your operation teams for cloud readiness.
Understanding dependencies between your applications and workloads is the second most important key. Migration strategies should meet and cover all of your business needs. Detailed application and infrastructure inventory should be in place and you should review every single component of your current environment to choose the correct migration strategy. There are seven common migration strategies: relocate, rehost, replatform, refactor, repurchase, retire, or retain.
Experimenting and training are the third key while migrating to AWS. Your teams should gain hands on experience in a controlled environment and be free as much as possible while considering business risks. You can improve your agility while maintaining governance and control over cost, compliance, and security.
Once your migration plan is solid, it is time to execute it. During the migration, each workload and application will be migrated one by one and validated per desired achievements and business outcomes that you have defined on the readiness assessment phase.
